TS79M00 series
3-Terminal Medium Current Negative Voltage Regulator
Pin assignment:
1. Ground
Voltage Range - 5V to - 24V
Output Current up to 0.5A
2. Input
3. Output
(Heatsink surface
connected to Pin 2)
General Description
The TS79M00 Series negative voltage regulators are identical to the popular TS7900 Series devices, except that they are
specified for only half the output current. Like the TS7900 devices, the TS79M00 Series 3-Terminal regulators are
intended for local, on-card voltage regulation.
Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine
to make these devices remarkably rugged under most operating conditions. Maximum output current with adequate
heatsink is 500mA
This series is offered in 3-pin TO-220, TO-252 package.
Features
Standard Application
Output current up to 0.5A
No external components required
Internal thermal overload protection
Internal short-circuit current limiting
Output transistor safe-area compensation
Output voltage offered in 4% tolerance
Ordering Information
A common ground is required between the input and the
output voltages. The input voltage must remain typically 2.0V
above the output voltage even during the low point on the
Input ripple voltage.

XX = these two digits of the type number indicate voltage.
* = Cin is required if regulator is located an appreciable
distance from power supply filter.
Note: Where xx denotes voltage option.
** = Co is not needed for stability; however, it does improve
transient response.
